IMPROVEMENT IN COKE'OVE NS.`

Specification forming part of Letters Patent No. 119,092, dated September 19, 1871.

To all whom it may concern: Be it known that I, THEoDoRE G. MEIER, of St. Louis, in the county of St. Louis and State of Missouri, have made certain new and useful Improvements in Coke-Ovens, and I do hereby declare that the following is a full and true description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The improvements here presented relate: First, to such a novel arrangementof vertical and horizontal ilues that each oven gives as well as receives heat, and whereby the gases are utilized and the generated heat is equally distributed to all parts of the oven. Secondly, to a peculiarlyconstructed right or left trough-shap ed tile, forming the upper and lower inlet and outlet connections with vertical and horizontal flues. Thirdly, in forminga skew-back tile with two horizontal holes and one diagonal hole or flue, whereby said tile is also made right or left in combination with trough-shaped tile. Fourthly, in arranging', in

a combination with vertical and horizontal ilues, a system of pipes to aid combustion of gases by the introduction of cold or hot air or steam; the arrangement and construction of all said parts being such that every oven can be operated separately or independent of adjoining ovens, and all of which will now be more fully described.

To enable those herein skilled to make and use my said` improvements I will now more fully describe the same, referring to the accompanying Figurel as a transverse sectional elevation at line y Fig. 2 as a longitudinal sectional elevation at line w1 y1; Fig. 3 as a top sectional plan at line .z2 y2,- Fig. 4 as a perspective oftrough-shaped tiles, showing reversed position of troughs in every other tile 5 Fig. 5 as a detail sectional elevation of skew-back tile; Fig. 6, detail bottom plan of same, Fig. 7, detail top plan of blast-pipe arrangements.

The oven is builiron a solid foundation, the top 'of which is nre-brick.y The sides or walls of the bottom chamber consisty of trough-shaped tiles B. Said tiles B are formed with troughs b. (See Figs. 1, 2, 3, and 4.) The bottom chamberA has horizontal iiues O Of, formed by the division-wall A1, upon the top of which the tile-floor A2 is built.

The said bottom floor `A2 of the coke-chamber may also be formed like an arch. In either case the trough-shaped tiles B are arranged with their troughs b alternately communicatingwith bottom chamber A or horizontal iiues O C. (See Figs. l and 3l) Every other trough-'tile B thus forms an opewside iiue for each adjoining chamber or horizontal lines when the ovens are built in pairs. Upon the row of said trough-tiles B are built the side walls D D of the oven, having vertical iiues d d so arranged as to discharge the gases into the horizontal iues C O through the trough-openings b of bottom tiles'. The smoke or consumed gases pass from thence into the smoke-stack in the rear of bottom chamber. On the top of side Walls are placed trough-shaped tiles E, formed with right or left troughs e, similar to bottom tiles B, but having a central vertical hole or iiue, e', as shown in Figs. l and 2. The tiles E thus formed are arranged reversed to bottom tiles B, but in a similar alternate manner, so as to receive the gases from the oven and conduct them through vertical iiues d d; from thence through horizontal nues.

On top of the trough-tiles E is arranged a row*l of skew-back bricks, F. These are formed with two horizontal holes, f f1, and having one diagonal hole, f2, arranged to connect with one of said horizontal holes, f, and also with vertical hole e in each of the trough-tiles E, in manner clearly shownin Figs. 1, 5, and 6. The said skewback tiles being also right or left, their horizontal holes f f1 form two longitudinal or continuous ilues, communicating, by means of their diagonals f2, with vertical and horizontal ilues. In order to facilitate combustion of gases cold or hot air, or steam, is introduced in each of the longitudinal iiues f f1, and similarly in the bottom horizontal dues O C. For this purpose main pipes G G are arranged in front or end of the oven, connecting, by branch pipes g gl, with horizontal iiues C G', and also connecting, by branch pipes g2 g3, with longitudinal flues ffl, in manner indicatedyin Figs. 2, 3, 7. As, therefore, the cold or hot air, or steam introduced is also, by means of the diagonal ilues f2, forced in the vertical iues d d', a complete combustion is insured, the heat generated being utilized beforel it passes into the smoke-stack. Each of the branch pipes g g1g/2 g3 rnrcn.

has proper stop-cocks; thus the combustion of the gases is under the control of the operator, and every oven can be shut off separately Without interferingwith the Working of the adjoining ovens.

The said system of pipes is operated either by suction or blast. The arch top H is built on top of skew-back bricks, and has proper'opening, in which coal is charged in the coke-chamber. The door in front may be arranged to Work in slides, or raised or lowered by chains connecting With a hoisting apparatus, or swung on hinges at the sides or top. When the coke is Well baked it may be drawn or forced out of the oven by a steamengine, as ordinary. The oven can readily be repaired. The construction is simple, cheap, and durable.

Having thus fully described my said improvements, what I claim and desire to secure by Letters Patent, is-

1. The arrangement and combination of horizontal ilues C C and vertical ilues d d to collect the gases, aid combustion, and extract heat and distribute the same to sides and bottom of the oven, substantially as and for the purpose set forth.

2. The alternate arrangement of vertical ues d df, by means whereof each oven gives and receives heat and each oven can be Worked separately of its neighbors, in combination with horizontal lues G C', substantially as shown and described.

3. The trough-shaped tile B having trough b, substantially as set forth.

4. The trough-shaped tile E having trough e and vertical hole e', substantially as set forth.

5. The trough-shaped tiles B and E, constructed as described, and arranged to serve as inlet to vertical ilues d d or outlet to horizontal lues C C', substantially as and for the purpose set forth.

6. The right or left skew-back tile F, having longitudinal holes ffl and diagonal hole f2, when arranged in combination With trou gh-shaped tiles E and vertical lues d d, substantially as and for the purpose described.

7. The combination of pipes G G', branch pipes g g1 g2 g With stop-cocks, when arranged in eonnection With longitudinal flues f f1, vertical iues d d', and horizontal flues C C', substantially as shown, and for the purpose set forth.

In testimony of said invention I have hereunto set my hand.

THEODORE G. MEIER.
